ramips: add support for UniElec U7621-01 UniElec U7621-01 is a router platform board, the smaller model of the U7621-06. The device has the following specifications: - MT7621AT (880 MHz) - 256 of RAM (DDR3) - 16 MB of FLASH (SPI NOR) - 5x 1 Gbps Ethernet (MT7621 built-in switch) - 1x 2.4Ghz MT7603E - 1x 5Ghz MT7612 - 1x miniPCIe slots (PCIe bus only) - 1x miniSIM slot - 1x USB 2.0 (uses the usb 3.0 driver) - 8x LEDs (1x GPIO-controlled) - 1x reset button - 1x UART header (4-pins) - 1x GPIO header (30-pins) - 1x DC jack for main power (12 V) The following has been tested and is working: - Ethernet switch - 1x 2.4Ghz MT7603E (wifi) - 1x 5Ghz MT7612 (wifi) - miniPCIe slots (tested with Wi-Fi cards and LTE modem cards) - miniSIM slot (works with normal size simcard) - sysupgrade - reset button Installation: This board has no locked down bootloader. The seller can be asked to install openwrt v18.06, so upgrades are standard sysupgrade method. Recovery: This board contains a Chinese, closed-source bootloader called Breed (Boot and Recovery Environment for Embedded Devices). Breed supports web recovery and to enter it, you keep the reset button pressed for around 5 seconds during boot. Your machine will be assigned an IP through DHCP and the router will use IP address 192.168.1.1. The recovery website is in Chinese, but is easy to use. Click on the second item in the list to access the recovery page, then the second item on the next page is where you select the firmware. In order to start the recovery, you click the button at the bottom. LEDs list (left to right): - ESW_P0_LED_0 - ESW_P1_LED_0 - ESW_P2_LED_0 - ESW_P3_LED_0 - ESW_P4_LED_0 - CTS2_N (GPIO10, configured as "status" LED) - LED_WLAN# (connected with pin 44 in wifi1 slot)
